AmpliTech completes initial phase of testing of 64T64R CAT-B Massive MIMO O-RU

AmpliTech Group (AMPG) completed the initial phase of rigorous testing of its advanced 64T64R CAT-B Massive MIMO O-RU during the O-RAN Global PlugFest Fall 2025. The company said, “This achievement makes AmpliTech the first and only U.S. company to bring a commercial-grade 64T64R radio into formal O-RAN lab testing, underscoring its leadership role in driving the next era of high-capacity, open, and disaggregated 5G networks…The Fall 2025 PlugFest included two coordinated laboratories, Digital Catapult and i14y Lab, operating identical hardware, software versions, configurations, and test conditions. This arrangement enabled consistent and repeatable testing, a key requirement for Open RAN adoption. AmpliTech’s 64T64R CAT-B O-RU participated in the Massive MIMO Beam Detection Test Scenario, conducted with G-REIGN which provided their DU/CU stack and the PlugFest’s Test Host Digital Catapult SONIC Labs. Next phase of the PlugFest will take place in Spring of 2026 in which the event participants will test end-to-end MIMO and Massive MIMO gNB functionality, verify beam detection, validate multi-vendor PHY and eCPRI integration, and prepare the system for broader commercial-grade interoperability.”
